MC10EL34DR2

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC10EL34DR2G is a low skew ÷2, ÷4, ÷8 clock generation chip designed for ECL applications. It features synchronous internal dividers with precisely aligned common output edges and a master reset input for system synchronization. The device supports PECL mode (VCC = 4.2 V to 5.7 V) and NECL mode (VEE = −4.2 V to −5.7 V). Key electrical parameters include a maximum toggle frequency of 1.1 GHz, 50 ps typical output-to-output skew, and 100 ps maximum within-device skew. Power supply current is typically 39 mA in both modes.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'R2' indicates tape and reel packaging containing 2500 units per reel. Confirm RoHS compliance by checking for the 'G' suffix (MC10EL34DR2G), which denotes a lead-free package. Ensure the specific part number matches the required packaging format before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when precise alignment of divided clock edges is required due to its synchronous divider architecture. Choose between the MC10EL34 (standard) or MC100EL34 (temperature compensated) variants based on thermal stability requirements. Ensure power supply configurations match either PECL (+5V) or NECL (-5V) specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MC10/100EL34 series of clock generation chips. The '10' prefix denotes standard performance, while '100' indicates temperature compensation. The DR2 suffix specifies the SO-16 surface mount package in tape and reel form factor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

MC100EL34DR2G offers temperature compensation compared to the standard MC10EL34 variant. Both share identical pinouts and functional characteristics but differ in thermal parameter specifications.
